problem with xhost

[Avinoam]

hello

you should add switches to the xhost command :

1. xhost + this one will enable session from all clients

2. xhost +192.168.1.100 this will enable session only from the client 192.168.1.100.

there is much better and secure way to do this by exchangeing the MIT MAGIC COOKIE , you can read about it here : http://csrc.nist.gov/publications/nistpubs/800-7/node90.html

good luck

Hi Stuart,

I login as root into the command line on the local computer.I have no firewall enabled.If I issue the xhost without setting the DISPLAY variable.I get the error message,
xhost: unable to open display ""

I really have no idea about that.

Regards,
James

There is no X running. That's why it's failing.

Looks like you didn't start the X at all.First of all you have to issue
the command: startx..If you had errors and the X didn't start, run: redhat-config-xfree86
which isa utility that configures the X.
If you want to start a program like xcalc (for example) on your pc from tty1-tty6
then before executing the xcalc run this command:
export DISPLAY=localhost:0
setting DISPLAY variables is ususally done when you want to tell your OS to open grafic programs on other computers.

Hello!

If you wanna run X client program you must!
run X server that the client will connect to
and then you will see it.
